solveit please please

Answer 1

Hope it is correct........

Answer 2

x=√5+√2/√5-√2

=(√5+√2) (√5+√2) /(√5-√2) (√5+√2)

=5+2+2√10/3

=7+√10/2

y=(√5-√2) /(√5+√2)

=(√5-√2) (√5-√2) /(√5+√2) (√5-√2)

=5+2-2√10/3

=7-2√10/3

x^2+xy+y^2

(7+2√10/3) ^2+(7-2√10) (7+2√10) +(7-2√10/3) ^2

=49+40+28√10/9+9+49+40-28√10/9

=178/9+9

=251/9

251 is your required answer
